UBI: fix error handling in ubi_scan()

Two bad things can happen in ubi_scan():
1. If kmem_cache_create() fails we jump to out_si and call
   ubi_scan_destroy_si() which calls kmem_cache_destroy().
   But si->scan_leb_slab is NULL.
2. If process_eb() fails we jump to out_vidh, call
   kmem_cache_destroy() and ubi_scan_destroy_si() which calls
   again kmem_cache_destroy().
